Smoke 2026-05-03 saw main-pm reach the git layer with a 'commit' call,
trying to author 'fix(gateway): allow claimed status in i_will_plan
preflight'. That should never have been possible — main_pm/cell_pm/
board/auditor/qa manifests all exclude commit. Reaching the verb body
means either the MCP manifest filter mis-routed, or the agent hit the
v2 do.py route directly.
Mirror Task 16 notify pattern: server-side role check in the verb body
rejects with not_authorized + 'PMs delegate, do not commit' remediate.
Defense-in-depth — manifest is still the primary gate.
Pre-gateway PMs/Board sent formal notifications (require ack); gateway
had say/dm only. Now PMs and Board can issue ack-required notifications
via NotificationService through the standard envelope path.
When a caller passes an explicit task_id to commit / note / say / dm /
evidence, ContentActions now verifies task.assigned_to == caller_agent_id
before allowing the side effect. Auto-fill from get_active_task_for_agent
is implicitly self-owned and does not need a re-check.
evidence() additionally allows assigned_to=None (post-handoff transient
state) so QA / documenter can inspect tasks between reassignments.
Pre-gateway, agents could not even see tasks they didn't own because the
MCP handlers resolved task from session context. The gateway exposes
task_id parameters across multiple verbs, so the explicit ownership
gate is required.
Exception: say() and dm() with NO task_id are exempt — used for channel
announcements and off-task A2A. The strict guard only applies when the
agent supplies a task_id parameter.
